Description

【０００１】
【発明の属する技術分野】
この発明は、パンツ型の使い捨ておむつに関する。
【０００２】
【従来の技術】
図１２の折りたたみ型使い捨ておむつ（おしめ）２０１は、特許文献１に開示されているものである。このおむつ２０１は、吸液性パッドと、液透過性内面シート２２２と、液不透過性外面シート２２３とからなる矩形のもので、長辺と直交する横断線２１０ａに沿って半分に畳んである。また、その横断線２１０ａにおける中心点の両側部分がおしめの内方ヘ向かって折り込まれ、ポケット２１８が形成されている。このおむつでは、それを着用させるときに広げてもポケット２１８の形状が崩れないように、折り込まれて互いに向かい合うシート２２３の表面どうしが部分的に接着されている。このようなおむつは、それが矩形のものであっても着用者の股部を覆う部位の幅が狭いから、その部位が股部によく密着して体液の漏れを防止することができる。
【０００３】
【特許文献１】
特開昭５０−３３０４４号公報
【０００４】
【発明が解決しようとする課題】
特許文献１に記載のおむつでは、折り込まれたシートの表面どうしが接着されることによって、折り込まれた部分におけるシートの形状を維持することができる。この公知技術のように、使い捨ておむつの股部被覆域において体液吸収部がその幅を狭くするように折り込まれているものでは、おむつを着用しているときにもその折り込まれた部位の形状を維持することが重要であり、この発明では、脚周り開口の近傍に弾性部材を有する使い捨ておむつにおいても、体液吸収部の折り込まれた部位の形状を確実に維持できるようにして体液の漏れを防ぐことが課題である。
【０００５】
【課題を解決するための手段】
前記課題を解決するためのこの発明が対象とするのは、互いに直交する高さ方向と幅方向と前後方向とを有し、前記幅方向を二等分して前記高さ方向へ延びる中心線に関してほぼ対称に形成され、内面側がおむつ着用者の肌と向かい合う一方、外面側が前記着用者の着衣と向かい合い、前記着用者の前胴周り域と後胴周り域と股部とを覆う前胴周り被覆域と後胴周り被覆域と股部被覆域とによってパンツ形状が画成されて胴周り開口と一対の脚周り開口とを有し、前記股部被覆域を中心に前記前後胴周り被覆域方向へ長く延びる体液吸収部が前記内面側に形成されているパンツ型の使い捨ておむつである。
【０００６】
かかる使い捨ておむつにおいて、この発明が特徴とするところは、次のとおりである。前記体液吸収部は、吸液性芯材と前記芯材の少なくとも一部を覆う透液性被覆シートとを含み、前記肌と向かい合う内面部分と前記内面部分とは反対側の外面部分とこれら両部分をつないで前記股部被覆域から前記前後胴周り被覆域へ延びる互いに並行な両側縁部分とを有する。前記股部被覆域における前記体液吸収部には前記側縁部分と側縁部分との間の中央部位に始まって前記前胴周り域方向ヘほぼＶ字形を画いて前記側縁部分のそれぞれにまで延びる第１折曲部と、前記後胴周り域方向へほぼＶ字形を画いて前記側縁部分のそれぞれにまで延びる第２折曲部と、前記第１，２折曲部の間において前記幅方向へ延びる第３折曲部とが形成される。前記中心線を挟む前記体液吸収部の少なくとも前記両側縁部分それぞれは、前記第３折曲部においては前記外面部分どうしが向かい合う方向へ、かつ前記第１折曲部と第２折曲部とにおいては前記内面部分どうしが向かい合う方向へ折曲されている。前記前後胴周り被覆域および前記股部被覆域のいずれかに設けられて前記脚周り開口の近傍において前記側縁部分と交差する方向へ延びる弾性部材のうちで、前記おむつの前側に位置するものが前記側縁部分と交差する部位は前記吸収部における前記側縁部分と前記第１折曲部との第１交差部位よりも上方に位置し、前記おむつの後側に位置するものが前記側縁部分と交差する部位は前記吸収部における前記側縁部分と前記第２折曲部との第２交差部位よりも上方に位置している。
【０００７】
この発明の実施態様の一つにおいて、前記脚周り開口の近傍に位置する弾性部材が前記脚周り開口の周縁部に沿って前記脚周り開口の頂部から下方へ向かって伸長状態で延びる脚周り弾性部材であって、前記脚周り弾性部材が前記おむつの前側に位置するものの下端部は前記第１交差部位よりも上方で終わり、前記脚周り弾性部材が前記おむつの後側に位置するものの下端部は前記第２交差部位よりも上方で終わっている。
【０００８】
この発明の実施態様の他の一つにおいて、前記脚周り開口の近傍に位置する弾性部材が前記おむつの前記幅方向ヘほぼ水平に延びている。
【０００９】
【発明の実施の形態】
添付の図面を参照して、この発明に係るパンツ型の使い捨ておむつの詳細を説明すると、以下のとおりである。
【００１０】
図１，２は、パンツ型の使い捨ておむつ１の斜視図と、おむつ１の部分破断正面斜視図である。おむつ１は、互いに直交する高さ方向と、幅方向と、前後方向とを有するもので、高さ方向は図２においておむつ１の幅を二等分している中心線Ａ−Ａが延びる上下方向に同じであり、前後方向は図１の矢印Ｐ，Ｑで示される方向であり、幅方向は図１の矢印Ｒ，Ｓで示される方向であって、パンツ型を呈する被覆部２と、体液を貯留するための体液吸収部３とからなる。
【００１１】
被覆部２は、不織布やプラスチックフィルム等のシート材料で形成され、おむつ着用者の肌と向かい合う内面２ａ　と、着衣と向かい合う外面２ｂとを有し、その着用者の前後胴周り部と股部とを前胴周り被覆域６と後胴周り被覆域７と股部被覆域８とによって覆うことができる。股部被覆域８では、前胴周りシート１０６と第１股部シート１０８とが重なり合い（図４参照）、前胴周りシート１０６の下端縁１０６ａが幅方向へ延びる直線を画いている。前後胴周り被覆域６，７は、おむつ１の両側部で合掌状に重なり合い、上下方向へ間欠的に並ぶ部位４で互いに接合され、これら被覆域６，７，８によって胴周り開口９と一対の脚周り開口１１とが画成されている。これら胴周り開口９と脚周り開口１１の縁部それぞれには、複数条の弾性部材１２，１３が伸長状態で取り付けられている。脚周り弾性部材１３は、おむつ１の前後において、脚周り開口１１の頂部１１ａから下方に向かって、前胴周りシート１０６の下端縁１０６ａの近傍にまで延びている前側の脚周り弾性部材１３ａと、頂部１１ａから後胴周りシート１０７の下端縁１０７ａにまで延びている後側の脚周り弾性部材１３ｂとを有する。脚周り開口１１の内側には、防漏堤７０が見える。
【００１２】
図２において、股部被覆域８は、不織布からなる第１股部シート１０８と、股部シート１０８の内側に位置して不透液性フィルムからなる第２股部シート１１７と、第２股部シート１１７の内側に位置して不織布からなる内面シート１１６とを有する。これらシート１０８，１１７，１１６の内側、すなわち被覆部２の内面２ａには体液吸収部３が設けられている。
【００１３】
体液吸収部３は、股部被覆域８を中心に前胴周り被覆域６と後胴周り被覆域７とに向かって長く延びる両側縁部分２６と、前後胴周りの被覆域６，７において胴周り方向へ延びる両端縁部分２７とを有する。両側縁部分２６は、股部被覆域８で幅が狭くなるように、おむつ１の幅を二等分して高さ方向へ延びる縦中心線Ａ−Ａに向かって折曲されている。側縁部分２６の外側では、防漏堤７０が吸収部３の両端縁部２７へ向かって長く延びている。
【００１４】
図３，４は、図１，２のおむつ１を接合部位４において剥離し、前後胴周り被覆域６，７をおむつ１の前方向と後方向へ延びる矢印Ｐ，Ｑの方向へ伸展したものの平面図と、その平面図におけるおむつ１の分解斜視図とである。伸展した状態のおむつ１には、縦中心線Ａ−Ａに直交し、図の上下方向の長さを二等分しておむつ１の幅方向へ延びる横中心線Ｂ−Ｂも示されている。図３のおむつ１は、縦中心線Ａ−Ａに関してほぼ対称であり、横中心線Ｂ−Ｂに沿って折り重ねられると図１のおむつ１となる。
【００１５】
図３，４に示されたおむつ１の被覆部２と吸収部３とにおいて、被覆部２は、前胴周り被覆域６と股部被覆域８の一部分とを形成する六角形の前胴周りシート１０６と、後胴周り被覆域７と股部被覆域８の一部分とを形成する六角形の後胴周りシート１０７と、股部被覆域８の大部分を形成する矩形の第１股部シート１０８とを有する。第１股部シート１０８は、その両端部が前後の胴周りシート１０６，１０７の内面（図４における上面）にホットメルト接着剤（図示せず）を介して接合されてこれら両シート１０６，１０７を連結している。第１股部シート１０８の内面側には矩形の不透液性フィルムからなる第２股部シート１１７が重なり、第２股部シート１１７の内面側には砂時計型の内面シート１１６が重なっている。図示例の第２股部シート１１７は、第１股部シート１０８とほぼ同形同大であるかまたはそれよりもやや小さく、内面シート１１６は、前後の胴周りシート１０６，１０７と第１股部シート１０８とが互いに連結して形成する砂時計型の形状とほぼ同形同大である。これらシート１０６，１０７，１０８，１１７および１１６は、互いに重なり合う部分において間欠的に接合している。前胴周りシート１０６と内面シート１１６との間、および後胴周りシート１０７と内面シート１１６との間には、胴周り弾性部材１２と、脚周り弾性部材１３とが伸長状態で取り付けられている。第１股部シート１０８は、前後の胴周りシート１０６，１０７の連結を主目的とするもので、その目的の限りにおいて第２股部シート１１７よりも小さくすることが可能である。
【００１６】
吸収部３は、芯材２１と被覆シート２２とを有し、その被覆シート２２が縦中心線Ａ−Ａに沿う幅方向中央部分と前後の端縁部分２７とにおいて被覆部２の内面２ａにホットメルト接着剤１２９を介して接合している。吸収部３の側縁部分２６の外側には防漏堤７０が形成されている。被覆シート２２は透液性の不織布や開孔プラスチックフィルムで形成され、芯材２１は粉砕パルプや高吸水性ポリマー粒子等の吸水性材料を適宜の力で圧縮することにより、また必要ならば圧縮したものをティシューペーパや親水化処理された熱可塑性合成繊維からなる不織布で覆うことにより形成されている。図示例の芯材２１は、全体として矩形を呈するように配置されているが、横中心線Ｂ−Ｂと一致する鎖線Ｒ（第３折曲線）と、縦中心線Ａ−Ａと横中心線Ｂ−Ｂとが交わる芯材２１の中央部から前胴周り被覆域６方向へほぼＶ字形を画いて両側縁部分２６にまで延びる鎖線Ｓ（第１折曲線）と、縦中心線Ａ−Ａと横中心線Ｂ−Ｂとが交わる中央部から後胴周り被覆域７方向へほぼＶ字形を画いて両側縁部分２６にまで延びる鎖線Ｔ（第２折曲線）とに沿って延びる溝２０ｒ，２０ｓ，２０ｔを有し、これらの溝２０ｒ，２０ｓ，２０ｔによって芯材要素２１ａ，２１ｂ，２１ｃ，２１ｄ，２１ｅ，２１ｆに分けられている。溝２０ｒと溝２０ｓとのなす角度はαであり、溝２０ｒと溝２０ｔとがなす角度はβである。図ではαとβの大きさが同じであるが、これらの角度α，βには、大小の差をつけることができる。股部被覆域８において、吸収部３の幅はその被覆域８の幅よりも狭いから、図１，２，３において脚周り開口１１を形成している被覆域８の側縁部分は、吸収部３の側縁部分２６を越えておむつ１の幅方向外方ヘ向かって広がり、開口１１を一周する脚周りフラップを形成している。各芯材要素２１ａ〜２１ｆは、これらを覆う被覆シート２２またはティシューペーパに対してホットメルト接着剤によって間欠的に接着しておくと、相互の位置が乱れない。
【００１７】
図３，４に示されるように重なり合い互いに接合されるシート１０６，１０７，１０８，１１７，１１６および吸収部３は、中心線Ｂ−Ｂに沿って吸収部３を内側にして折り重ねられ、重なり合う前胴周りシート１０６と後胴周りシート１０７と内面シート１１６の側縁部どうしが図３に示される部位４で接合されると、パンツ型の使い捨ておむつ１となる。このように折り重ねるときに、吸収部３は、縦中心線Ａ−Ａの両側部分が、図２に示されているように縦中心線Ａ−Ａに向かって折曲される。すなわち、吸収部３は、芯材要素２１ｃと２１ｅの外面２４（図３参照）に相当する部分どうしが向かい合い、芯材要素２１ｄと２１ｆの外面２４に相当する部分どうしが向かい合うように溝２０ｒに相当する鎖線Ｒに沿って折曲され、その折曲と同時に、芯材要素２１ａの内面２３に相当する部分と芯材要素２１ｃ，２１ｄそれぞれの内面２３に相当する部分とが向かい合い、芯材要素２１ｂの内面２３に相当する部分と芯材要素２１ｅ，２１ｆそれぞれの内面２３に相当する部分とが向かい合うように、鎖線Ｓに沿って吸収部３の前方寄りに形成されて幅方向中央部から側縁部分２６にまで延びるほぼＶ字形の折曲案内部と鎖線Ｔに沿って吸収部３の後方寄りに形成されて幅方向中央部から側縁部分２６にまで延びるほぼＶ字形の折曲案内部とにおいて折曲される。
【００１８】
おむつ１では、鎖線ＲとＳとＴとを案内部にして折曲された吸収部３に、これらの鎖線Ｒ，Ｓ，Ｔと側縁部分２６とが交わる交差部位Ｗ，Ｘ，Ｙが鋭角の交差部位となって現れて（図２，３参照）、側縁部分２６は、交差部位Ｗを中心とするＸからＹへ至る間の部分がおむつ１の幅方向内方へ向かって延びている。かかるおむつ１を着用すると、交差部位ＸとＹとの間の側縁部分２６が着用者の大腿部の内側にあって、縦中心線Ａ−Ａへさらに近づくようにおむつ１の内方へ押しやられるように動き、そのときに交差部位ＸやＹが、脚周り開口１１の内側へ向かって図２に矢印Ｍで示される方向ヘ動くことがある。脚周り開口１１の頂部１１ａから延びた前後の脚周り弾性部材１３ａ，１３ｂは、それらの下端部４０ａや４０ｂが交差部位ＸやＹを越えて下方へ延びていると、交差部位ＸやＹの近傍が矢印Ｍ方向へ動くことに伴い、脚周り弾性部材１３は、交差部位Ｘ，Ｙの近傍において着用者の脚周り方向へ延びるのではなくて、おむつ１の外側から内側へ向かって延びるようになり、特におむつ１の後側では股部被覆域８の両側部分がおしりにくい込むような状態になることもある。そのような状態になったときの交差部位Ｘ，Ｙの近傍は、脚周りに密着し難くて体液が漏れ易くなる。しかしながら、このおむつ１の脚周り弾性部材１３は、前側の脚周り弾性部材１３ａの下端部４０ａが側縁部分２６と交差する方向へ延びて、交差部位Ｘの上方で終わり、側縁部分２６と交差する部位は交差部位Ｘよりも上方、好ましくは５ｍｍ以上上方に位置し、後側の脚周り弾性部材１３ｂの下端部４０ｂも側縁部分２６と交差する方向へ延びて、交差部位Ｙの上方で終わり、側縁部分２６と交差する部位は交差部位Ｙよりも上方、好ましくは５ｍｍ以上上方に位置するから、交差部位ＸやＹの近傍が矢印Ｍ方向へ動いても、脚周り弾性部材１３ａ，１３ｂの下端部４０ａ，４０ｂも矢印Ｍ方向へ動いておむつ１が漏れやすいものになるということはない。ただし、体液の漏れ防止を一層確実にするために、このおむつ１は、吸収部３の側縁部分２６の外側に、吸収部３の長手方向ヘ弾性部材７１（図３参照）が伸長状態で取り付けられている防漏堤７０を有する。防漏堤７０は、この弾性部材７１の収縮によって、股部被覆域８の内側において、上方へ向かって起立しておむつ着用者の脚周りに下方から密着することができる。

【００２３】
図１０は、この発明の実施態様の一例を示す図９と同様な図面である。このおむつ１では、前胴周りシート１０６または後胴周りシート１０７の下端部にのみ設けられた補助弾性部材５３が吸収部３を横切って左右の脚周り開口１１の縁部にまで延びている。かような補助弾性部材５３は、その全長が伸長状態にあってもよいし、吸収部３を横切る部分だけは非伸長状態であってもよいもので、図において一番下の補助弾性部材５３ａは、吸収部３の交差部位Ｘの上方、より好ましくは少なくとも５ｍｍ上方において側縁部分２６と交差している。
【００２４】
図１１は、この発明の実施態様の一例を示す図８と同様な図面である。このおむつ１が図８のそれと異なるのは、前胴周りシート１０６と後胴周りシート１０７とが六角形ではなくて矩形に作られ、内面シート１１６がその矩形とほぼ同じ大きさの胴周り被覆域を持つように作られていることである。補助弾性部材５３のレイアウトは、図８のレイアウトと実質的に同じであり、図において一番下の補助弾性部材５３ａは、吸収部３の交差部位Ｘの上方、より好ましくは少なくとも５ｍｍ上方において側縁部分２６と交差している。この図のおむつ１では、補助弾性部材５３のレイアウトを図示例のものに替えて、図９，１０のものを採用することができる。
【００２５】
この発明において、図示例の脚周り弾性部材１３や補助弾性部材５３は、いずれも吸収部３の交差部位Ｘ，Ｙよりも上方で側縁部分２６と交差していたが、弾性部材が交差部位Ｘ，Ｙの側方に位置する場合には、それらの弾性部材を交差部位Ｘ，Ｙから少なくとも５ｍｍ離間させることが好ましい。また、脚周り弾性部材１３や補助弾性部材５３のレイアウトは、前胴周りシート１０６のそれと後胴周りシート１０７のそれとで異なっていてもよい。例えば、前胴周りシート１０６には図６のレイアウトを採用し、後胴周りシート１０７にはその他の図のレイアウトを採用することができる。
【００２６】
【発明の効果】
この発明に係るパンツ型の使い捨ておむつは、股部被覆域を中心に前後胴周り被覆域へ向かって延びる体液吸収部の側縁部分が股部被覆域において幅が狭くなるようにおむつの幅方向内方ヘ折曲されている。脚周り開口の近傍に位置する弾性部材は、吸収部をおむつの幅方向内方ヘ折曲することにより吸収部の側縁部分に生じた折曲案内線との交差部位よりも上方において側縁部分と交差しているから、おむつを着用しているときに交差部位の近傍でそれらの弾性部材が脚周り開口の内側へ引き込まれて脚周りのシールが不十分となり体液が漏れやすくなるという問題を防ぐことができる。

Between the front waistline sheet 106 and the inner sheet 116, and between the rear waistline sheet 107 and the inner sheet 116, a waist elastic member 12 and a leg elastic member 13 are attached in an extended state. . The main purpose of the first crotch sheet 108 is to connect the front and rear waist sheets 106 and 107, and it is possible to make the first crotch sheet smaller than the second crotch sheet 117 as far as the purpose is concerned.
[0016]
The absorbing portion 3 has a core material 21 and a covering sheet 22, and the covering sheet 22 is provided on the inner surface 2 a of the covering portion 2 at a widthwise central portion along the longitudinal center line A-A and front and rear edge portions 27. They are joined via a hot melt adhesive 129. On the outer side of the side edge portion 26 of the absorbing section 3, a leak barrier 70 is formed. The cover sheet 22 is formed of a liquid-permeable nonwoven fabric or a perforated plastic film, and the core material 21 is formed by compressing a water-absorbing material such as pulverized pulp or highly water-absorbing polymer particles with an appropriate force. It is formed by covering the woven fabric with tissue paper or a nonwoven fabric made of a thermoplastic synthetic fiber subjected to hydrophilic treatment. Although the core material 21 in the illustrated example is arranged so as to present a rectangle as a whole, a chain line R (third bent line) matching the horizontal center line BB, a vertical center line AA and a horizontal center line A dashed line S (first folding line) extending substantially from the center of the core material 21 where BB intersects toward the front waistline covering area 6 and extending to both side edge portions 26, and a longitudinal center line AA A groove 20r extending along a chain line T (a second fold curve) extending substantially from the center where the horizontal center line BB intersects the rear waistline covering area 7 and extending to both side edge portions 26; The grooves 20r, 20s, and 20t are separated into core elements 21a, 21b, 21c, 21d, 21e, and 21f. The angle between the groove 20r and the groove 20s is α, and the angle between the groove 20r and the groove 20t is β. Although the magnitudes of α and β are the same in the figure, the angles α and β can be different in magnitude. In the crotch covering region 8, the width of the absorbing portion 3 is smaller than the width of the covering region 8, so that the side edge portion of the covering region 8 forming the leg opening 11 in FIGS. The diaper 1 extends outward in the width direction of the diaper 1 beyond the side edge portion 26 of the portion 3 and forms a leg flap surrounding the opening 11. If the core elements 21a to 21f are intermittently bonded to the covering sheet 22 or tissue paper covering them with a hot-melt adhesive, their mutual positions are not disturbed.
[0017]
As shown in FIGS. 3 and 4, the sheets 106, 107, 108, 117, 116 and the absorbing portion 3 which are overlapped and joined to each other are folded and overlapped with the absorbing portion 3 inside along the center line BB. When the side edges of the front waistline sheet 106, the rear waistline sheet 107, and the inner sheet 116 are joined at the portion 4 shown in FIG. 3, the pants-type disposable diaper 1 is obtained. When folded in this way, the absorbing portion 3 is bent on both sides of the vertical center line AA toward the vertical center line AA as shown in FIG. That is, the absorbing portion 3 is formed in the groove 20r so that portions corresponding to the outer surfaces 24 of the core elements 21c and 21e (see FIG. 3) face each other, and portions corresponding to the outer surfaces 24 of the core elements 21d and 21f face each other. The core element 21a is bent along the corresponding chain line R, and at the same time, the part corresponding to the inner surface 23 of the core element 21a and the part corresponding to the inner surface 23 of each of the core elements 21c and 21d face each other. The portion corresponding to the inner surface 23 of the core 21b and the portion corresponding to the inner surface 23 of each of the core elements 21e and 21f face each other along the dashed line S toward the front of the absorbing portion 3 and extend from the center in the width direction to the side. A substantially V-shaped bent guide portion extending to the edge portion 26 and a substantially V-shaped bent plan formed toward the rear of the absorbing portion 3 along the chain line T and extending from the center in the width direction to the side edge portion 26. It is bent in a part.
[0018]
In the diaper 1, the intersections W, X, and Y where the chain lines R, S, and T intersect with the side edge portions 26 are formed at acute angles in the bent absorbing portion 3 with the chain lines R, S, and T as guides. (See FIGS. 2 and 3), and the side edge portion 26 extends inward in the width direction of the diaper 1 in a portion between X and Y around the intersection portion W. I have. When such a diaper 1 is worn, the side edge portion 26 between the intersections X and Y is inside the thigh of the wearer, and inward of the diaper 1 so as to be closer to the vertical center line AA. It moves so that it may be pushed, and at that time, the intersections X and Y may move toward the inside of the leg opening 11 in the direction indicated by the arrow M in FIG. The front and rear leg elastic members 13a and 13b extending from the top 11a of the leg opening 11 have a lower portion 40a or 40b extending downward beyond the intersection X or Y. As the vicinity moves in the direction of arrow M, the leg elastic members 13 do not extend in the direction of the wearer's legs in the vicinity of the intersections X and Y, but extend from the outside to the inside of the diaper 1. In particular, on the rear side of the diaper 1, both sides of the crotch covering area 8 may be in a state in which it is hard to push down. In such a state, in the vicinity of the intersections X and Y, it is difficult to closely adhere around the legs, and the body fluid easily leaks. However, the leg surrounding elastic member 13 of the diaper 1 extends in a direction in which the lower end portion 40a of the front leg surrounding elastic member 13a crosses the side edge portion 26, ends above the intersection X, and ends with the side edge portion 26. The intersecting portion is located above the intersecting portion X, preferably 5 mm or more, and the lower end portion 40b of the rear leg elastic member 13b also extends in the direction intersecting the side edge portion 26, and is located above the intersecting portion Y. Ends, the portion intersecting with the side edge portion 26 is located above the intersection portion Y, preferably 5 mm or more. Therefore, even if the vicinity of the intersection portion X or Y moves in the direction of the arrow M, the leg elastic member 13a , 13b do not move in the direction of arrow M so that the diaper 1 does not easily leak. However, in order to further prevent leakage of bodily fluids, the diaper 1 is provided with an elastic member 71 (see FIG. 3) extended in the longitudinal direction of the absorbing portion 3 outside the side edge portion 26 of the absorbing portion 3. It has a leak barrier 70 attached. Due to the contraction of the elastic member 71, the leak-prevention embankment 70 can stand up from the inside of the crotch-covered area 8 and adhere to the circumference of the diaper wearer's leg from below.
[0019]
